IBM Streams 4.3.0

User authentication errors on SLES systems

If you are running IBM® Streams on SUSE Linux Enterprise Server (SLES), IBM Streams users might have authentication problems.

Symptoms

You are not able to authenticate when prompted by the streamtool command or when you attempt to log in to the Streams Console. The following message is displayed:

  CDISR2503E The specified user name or the specified password is not valid.

Causes

By default, SLES uses the PAM UNIX2 backend, which prevents IBM Streams from authenticating a user ID and password.

Resolving the problem

To resolve this problem, IBM Streams users can generate RSA keys for authentication or a user with root authority can update the PAM configuration. For instructions, see IBM Streams user authentication issue on SLES systems.
